DRILL FOR GRAIN OR FERTILIZER.

Specification of Letters Patent.

Patented Feb. 15,1916;

Application filed August 18, 1914. Serial No. 857,426.

To all whom it may concern Be it known that I, GEORGE M. WINWOOD, Jr., citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Drills for Grain or Fertilizer; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Wlll enable others skilled in the art to which it appertains to make and use the same.

This invention relates to seeders and planters, and more especially to those which employ a furrow-opening disk; and the object of the same is to improve the construction of the boot so'that it may drop grain having kernels of various size or so that it may drop fertilizer whether the same be moist or dry.

With" this'object in view the invention consists in the construction hereinafter more fully described and claimed and as shown in the drawings wherein Figure 1 is a left side elevation of this device. complete, showing in dotted line the means for attaching it to the drag bar or frame of the machine. Fig. 2 is a left side elevation of the boot with its cover plate in place, and the disk removed. Fig.3 is a similar side elevation with the cover plate removed, and Fig. 4 is a detail of said plate. Fig. 5 is a rear elevation of the complete device. Fig. 6 is a vertical section, and Fig. 7 a horizontal section on the lines 66 and 77 respectively of Fig. 2. Fig. 8 is an enlarged sectional detail of the bearing for the disk. Fig. 9 is a cross-section of the boot on the line 99 of Fig. 5.

Inthe drawings the letter D designates the-disk which may be of any approved material and size, and is by preference slightly concavo-convex as shown, the letter B designates'the upper end of the boot which communicates with the seed tube or other tube leading from the hopper on the frame of'the machine (not shown), and the letter C indicates the connections illustrated in dotted lines in Fig. 1 by means of which ears E and E on the boot are connected with the drag bar or framework in any suitable manner. One of these cars is front of the boot and inclined upwardly as shown at E, being pierced with holes by means of which the connecting rod C may be attached thereto, and the other ear E is in rear of the boot andhas a similar hole or eye for the rearcasting, its body lnear the upper'portion thereof comprising three walls extending, around three sides of a practically rectangu l aill openingthrough' which the seed' may upward, and in thef'an'gle between said wall and ear"i's an oil"'cup2 preferably closed 3, the interior of the cup by a screw plu communicating" by a. duct" 4 (shown in p 165 The front ear projects forward from the front wall of the body'and slightly j dotted lines) with'the interior of a bearing.

5 ;for the disk D which is best shownpin Fig. 1. Beneath this bearing the "front wall of the body 1 is continued forward intoa web 6 whose edge 7 restsagainst' and acts as a scraper for the convex sid'e 'of thedisli D whenthe latter isin place. Thbutei wall of the body 1 approachesthe disk" near]:

the lower end of the channeled "boot as seen at 8, the web and its'scraping edge 7 closing the front of the channel against the disk',,'.,

and the lower edge, ofthe rear wall9 being exposed and standingslightly' remote from said disk as seen in'5. Tljierefore whats ever is delivered by the channel isdropp e d" out the lower'end or out'tlie rearside there of against the convex sideof'the disk? The closure for this channeled boot consistsof a cover plate 10 best seen in Fig'f'fi, the same bemg by preference another piece of rough iron casting curved slightly in trans verse section and shaped to fit ag 'ainst'th e edges of the front and rear'walls' of the channeled member or body portion 1. Sam walls may have lugs 11 near their-"upper ends for engaging the side edges of the" cover 10 when the latter is in place; The,

cover'is pierced with a l1ole 12through which passes a screw 13 whose inner end engages a threaded opening or hole 14 'in the outer wall of the body 1 tohold the two members together,'and below said hole the cover is externally shaped to lie closely l 1 cover is shaped to complement with the.

against the disk. The lower end of said lower end of the main or' body member and its extremity is preferably cut 03 on" a. bevel as shown at 15 so as toexpose quitei an opening at the lower end'of the'channel for the dropping of seed. But the rear side edge of thiscover member has'a up 16 bent inward and contacting with the edge of the rear Wall of the body member when the cover member is employed. When this cover member is not employed it will be clear that there is quite a space between said rear wall 9 and the contiguous face of the disk D, for the purpose set forth below.

While it may be possible to mount the disk in any suitable manner, I prefer the hereinafter described construction for the reason that it can be adopted in a casting which is otherwise of rough and cheap material. That is to say, the disk has a hub riveted to its concave side as seen at 21, and from the center of the hub a stub-shaft 22 projects rearward through the hole in the disk for a considerable distance, the hub and the shaft being tubular. Mounted between the hub and the concave side of the disk and projecting into the hole of the same is a felt or other washer, 2 for preventing dirt and particles ,,of,, tone from getting onto the bearing.

The socket within the bearing-5 is of a size to receive the stub-shaft 22 rather closely but so that the latter may rotate easily therein, and this socket by preference extends entirely through the boot-casting and has its rear end closed in any suitable manner as shown at 25, the inner end of the socket near the closure being enlarged as illustrated at 26 and communicating with the duct 4 above described. Within the enlarged portion is located the head 27 of a bolt 28 whose shank passes centrally through the bearing and through the bore within the hub of the disk, and receives the nut 29 at the dished side of the disk as illustrated. \Vhen this nut is removed the disk and its stub-shaft come freely out of place, and access to the interior of the bearing may be had. At other times or when it is desired to use the disk, it is only neces sary to place its stub-shaft within the socket of the bearing 5 and pass the tip of the bolt through the bore of the shaft and the hub 20, and when the felt washer has been brought up against the end of the hub, the nut is applied to the bolt and the device is ready for use.

Oil applied to the cup 2 flows down the duct 4 and reaches the interior of the bearing and oils the parts where friction might arise.

YVith a device constructed as above described and applied to the frame work of a machine, and the seed tube leading downward from the hopper into the upper end of the boot in a manner well understood, the forward progress of the machine draws the cutting edge of the disk D through the soil and opens a furrow, being assisted by the scraper 7 which also serves the function of holding the furrow open until the seeds are dropped into the same. Moreover the scraper keeps the convex side of the disk clear, and its close proximity to said side prevents the passage between these elements of weeds, stalks, and other objectionable matter which would interfere with the free. dropping of the seeds. The latter fall through the boot and out the opening between the beveled lower end 15 of the cover plate 10 and the channeled member, and are deposited in the furrow in a manner well understood. If the size of the kernels being dropped is such that they do not pass freely out this opening, it is quite possible to replace the cover plate 10 with another whose beveled end 15 is disposed farther up or is differently formed so that thereis a free outlet for the seed. To substitute another cover plate it is necessary only to remove the disk in the manner above described, then take out the screw 13, lift off the plate 10, replace it by another, and reassemble the parts.

When now it is desired to use this improved device for dropping fertilizer which may be quite lumpy and perhaps on occasions moist. I would omit the plate entirely. The fertilizer being placed in the hopper of the machine and delivered into the top of the boot, it falls between the open side of the channeled body member 1 and the convex side of the disk; and although the latter is disposed quite some distance from the edges of the walls of the channeled member 1, it is not so far away that it does not prevent the escape of the fertilizer, while its rotation when in action causes agitation thereof. The result is that the fertilizer falls down within the channeled member until it passes the bearing 5 and below this point the disk is moving to the rear; and therefore the disk rolls or forces the fertilizer out the space between its convex surface and the cut-away rear wall 9 of the main casting, which space is left when the cover plate 10 and its lip 16 are removed. From this description it will be clear that while the cover plate closes a channel which at its upper portion is composed of another wall and front and rear walls, said outer wall 8 approaches the cover plate at the lower end of the boot and the rear wall 9 recedes from said plate. The effect is that the cover plate closes the open side of the channel adjacent the disk down to the line 15 at its lower end; but when the plate is removed there is an exit of considerable size for the lumpy and perhaps damp fertilizer, and there is also present the agitator and (we might also say) ejector which is the moving disk itself. This construction adapts my drill for dropping grain having various sizes of kernels, or larger material such as fertilizer, even though the latter be moist and to an extent lumpy.

The materials and proportions of parts other than as to details hereinbefore described, are not essential.

What is claimed as new is:

l. The combination with a furrow-opening disk; of an upright boot comprising a channeled body member standing alongside the disk with the edges of its front and rear walls wholly out of contact therewith excepting for a scraper on the front wall below the disk-pivot, and a second member removably insertible between the disk and the first member for closing the upper portion of its channel, for the purpose set forth.

2. The combination with a furrow-opening disk; of a boot composed of a channeled body member standing upright alongside the disk with its outer Wall approaching the disk at the lower end of the channel, a cover plate adapted to overlie and close said channel and having its lower end cut off oblique and its rear edge formed into a lip closing against the rear wall of the body member, and means for removably attaching the two members.

3. The combination with a concavo-convex furrow-opening disk; of a boot comprising a channeled body member standing upright alongside the disk with its front wall having a scraping edge contacting therewith and its rear wall spaced from and out of contact with said disk, and a cover plate removably attached to the body member and shaped to close the open side of the same except at its rear end and fit closely against the convex side of said disk.

In testimony whereof I aflix my signature in presence of two witnesses.
